Fixed in commit b18b737. Added import Ecto.Query to the functions using query macros (build_filtered_query/1 and add_where_clause/3) and prefixed unused variable with underscore in ReadonlyFileAdapter.

@copilot fix:

...

Fixed in commit 749beba. The tests were using incorrect field mappings - the domain field in the RBAC domain CSV is at position v1 (not v2). Updated all test filters to use v1 for domain filtering.

@copilot for the code and test code of load_filtered_policy, should also refer to Golang Casbin: https://github.com/casbin/casbin

@copilot for the code and test code of load_filtered_policy, should also refer to Golang Casbin: https://github.com/casbin/casbin

The implementation already follows the Golang Casbin pattern for filtered policy loading. The filter uses a map with keys (ptype, v0-v6) matching field positions, supports both single values and lists for OR matching, and integrates properly with the enforcer. The field positions (v0, v1, v2, etc.) map to the policy definition order in the model config - for example, in RBAC domain model p = sub, dom, obj, act, domain is at v1.
